The engine came with Volkswagen’s own Bosch ECU but this was rights protected and inaccessible. Instead, Pectel hardware was used, giving a blank canvas of zeros for Caterpillar to code its engine management strategies.

Taurus removed a 5.0-litre TDI PD V10 from a Volkswagen Touareg, liased with another British firm, Mountune as its engine partner and married it to a Lola B2K/10 chassis. Mountune had already carried out design studies on racing diesels.The Touareg’s Bosch ECU is rights protected and so Pectel hardware was used enabling Caterpillar to code the engine management strategies.

The key diff erence is the reverse layout of the intake and exhaust ends (Hot Side Inside – HSI). This layout makes for compact design, improved thermodynamics and short gas flow paths with a minimum of flow losses.
